Here's my Brainy Tribute build. I didn't interact with Andy that much, but I enjoyed reading his posts, and I figured I'd join in paying my respects. This is going to be a Thinline with a few quirks, including a feature that I think just might be a world first. Stay tuned. To recap, here's the piece of mystery wood I salvaged from a 150-year old barn with a leaking roof. I actually got two pieces, the one not in the picture being narrower but otherwise just as exciting piece of dirty wood. At this point I thought they might be birch. Here's one of the planks after planing. It was cupped and cracked so badly that I had to rip it down the middle. The heartwood tells me it's not birch, but what is it then? My best guess so far is bird cherry (Prunus padus), with rowan aka European mountain ash (Sorbus aucuparia) a close second. Someone suggested maple, but it's not hard enough for that, and I don't think any maple has brown heartwood. Any other guesses? I was planning to use the mystery wood for the body, but on closer inspection it seems I can only get a usable 31-32 mm (1 1/4") thickness out of it. I guess I could always put a 6 mm (1/4") cap on both sides, but I was kind of hoping to have the mystery wood more visible. Not sure if I can make it happen with these pieces (I still have some left unplaned) unless I make it a 4-piece. At this point I'm open to any ideas, I'm making it up as I go along anyway.
